CSIR-NML has both the art of facilities and expertise in the areas of non-destructive evaluation (NDE). Developed through a partial funding from Department of Science & Technology (DST), Govt. of India in 2003, it is now a NDE centre for excellence in India. Some of the key industrial partners of this centre are ISRO, NTPC, Tata Steel, Boeing, IOCL, Bharat Forge, BARC, Aditya Birla.

Damage evaluation using NDE:

Damage evaluation using NDE

Over the years this group has developed different NDE based methodologies for characterisation of microstructure and assessment of different kinds of damage (residual stress, creep, fatigue, corrosion etc) in various grades of industrial materials. Substantial research activities have been carried out at CSIR-NML for last two decades on NDE and magnetic materials and as a result couple of portable, site-worthy devices have been developed for damage assessment of industrial components. This group is having more than 70 publications, 10 patents, transferred four and commercialised two technologies.

Sensors and Devices for Industrial applications:

Need based development of NDE sensors and devices for specialised industrial applications are an integral part of this group activity. This group has developed low cost defect detection system FlawGuard for moving wire. Technology has been transferred and one system has been commissioned at one of the biggest wire manufacturer in India. Present focus of this group is to develop sensor and device for online coating thickness measurement of Galvanised wire, sensing device for long range pipe inspection and high temperature sensor for real time structural health monitoring of components operated at temperatures >600oC.

Advanced magnetic/nanocrystalline materials:

Advanced magnetic/nanocrystalline materials

Another important activity of this group is the development of advanced magnetic materials which include rapidly solidified amorphous/ nanostructured soft magnetic alloys, magnetic shape memory, magnetocaloric materials and advanced materials (brazing, jewellery etc) in the form of ribbon, wires and rods as per application requirement.
